Signal Conditioners and Isolators from Marki Microwave : 4 - Page 1

Signal Conditioners and Isolators are essential components in industrial automation and control systems. They are used to convert, amplify, filter, or isolate input signals from sensors or field devices—such as temperature sensors, pressure transmitters, or voltage/current sources—into standardized output signals (e.g., 4–20 mA, 0–10 V) that can be accurately read by PLCs, DCSs, or data acquisition systems. Isolators also provide electrical isolation between input and output, helping to eliminate ground loops, reduce electrical noise, and protect equipment from surges or faults, thereby enhancing the overall reliability and safety of the system.
